Abstract

This invention relates to an AC magneto voltage regulation and rectifier circuit. It includes a sampling module to acquire a sampled voltage signal from the load; a comparison and control module to compare the sampled voltage signal with a preset reference voltage signal, and output a first control signal when the sampled voltage signal is greater than the reference voltage signal; a zero-crossing comparison to be performed on the AC signal output by the three-phase AC magneto, and a rectification control signal to be output based on the zero-crossing comparison result; a rectification and voltage regulation module to rectify the AC signal output by the three-phase AC magneto according to the rectification control signal to obtain a DC signal and provide the DC signal to the load; and a voltage regulation module to regulate the AC signal output by the three-phase AC magneto according to the first control signal. This invention only includes a rectification and voltage regulation module, an acquisition module, and a comparison and control module. Compared to traditional voltage regulation rectifiers, the circuit structure is simpler and the cost is reduced.
